Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] According to the characteristics of the industry, the entire process is split into several associated sub-process models, which can be normalized into flexible manufacturing models. According to the flexible manufacturing model, the invention develops a set of computing methods based on the Giffler&Thompson algorithm.
[0022] [basic concept]
[0023] Release plan: According to the production task requirements, the manufacturer will issue a production plan for the output quantity of a certain type of product on a monthly or weekly basis.
[0024] Execution plan: For the release plan, the factory should formulate the processing time and processing sequence of each workpiece, and the processing time and sequence of each machine.
[0025] Process: The order in which products are processed in each section of the entire production process....

The invention relates to a configurable sectional type-type production task scheduling method, which comprises the following steps: 1) firstly, according to the practical technological process of a factory, segmenting the technological process into a plurality of associated parts; 2) establishing a virtual connection pool among all sub technologies, determining the input / output contents of the connection pool, and finishing the information transfer of an upper-level technology and a lower-level technology; 3) according to the specific technological process, establishing a model by each sub technology, and determining the input / output parameter of the model; 4) according to a given format, inputting a releasing plan parameter on the first sub technology; 5) observing an output result to obtain execution plans and the specific parameter value of each execution plan in the technological process of the execution plan; and 6) according to practical requirements, regulating the parameters, and optimizing the execution plan. The configurable sectional type production task scheduling method is applied to the manufacture execution system software of an industrial site, and carries out controllable generation according to different releasing plan input parameters and technological processes.
Description
technical field [0001] The invention relates to the field of computer application technology, in particular to a configurable segmented production task scheduling method for generating execution plans according to different process characteristics and adjusting the execution plans according to input parameters in manufacturing execution systems on industrial sites. Background technique [0002] In manufacturing execution system software, the generation of execution plans will directly affect production efficiency and product output time. In some industries, due to numerous production processes and complex production processes, ordinary execution plan generation methods lead to low production efficiency. The released plan cannot be delivered on time, resulting in economic losses. In order to improve production efficiency, it is very necessary to provide a method of modeling according to process characteristics and adjusting the execution plan according to parameters.
